push_back struct c++

In C++, the push_back function is used to add an element to the end of a vector. When dealing with a vector of structs, the push_back function works the same way as it does with any other type. You simply call the push_back function on the vector and pass in the struct object that you want to add. The vector will then automatically resize itself to accommodate the new element, and the struct will be added to the end of the vector. This is a convenient way to dynamically grow a collection of structs as needed.
